I've started an online analogue camera & film shop with a friend, launched Dec 2010. Our target market is Lomography but our broader vision is to "keep film alive". I'm hesitant to post as I realise Lomography is frowned upon amongst many photographers as it's generalised that it's a marketing campaign to suck in young people into purchasing overpriced cameras - but my view is that I think it's a great thing as it's a catalyst to spark peoples interest into film.
Anyway the reason for my posting is because we are looking to expand our supply of films, at this stage it is purely limited to 135 and 120.
Seeing as there is so many choices available for us even when limited to just 135 and 120, I wanted to get some opinions as to what you guys currently use the most from these two film types. We will be doing both color and b&w. Look forward to your responses!
